T 0 all whom it may concern:

Be it known that I, JULns RonAIN MAR- TINET,.of Chemin Moyrand, Grenoble, Isere,

France, a citizen of the French. Republic, have invented Machines for Dyeing Hides, of which the following is a full, clear, and exact descriptioni- I This invention relates to a machine allowing to obtain the dyeing of hides by means of brushes, sponges, etc, and is essentially constituted by a horizontal table so arranged as to receive through a. suitable mechanism an intermittent rotary angular movement about a vertical axis and composed of a number of sectors which, adapted to each support a hide to be dyed come, during the rotation of the table, successively V opposite standing operators placed. around the said table and each specialized in an operation of the dyeing.

In its preferred form of construction. the table is driven by 'a piston receiving, in a cylinder, a reciprocating movement. under the action of a driving fluid, such thatsteam or compressed air alternately admitted on one andthe other faceof the piston bya: rotary distributor; the rod of this plston' forms a rack constantly in gear with a toothed segment rigid with a ring or crown carrying pawls soarranged as to come in engagement with the notches of a crown rigid with the table and to actuate'the latter, during the displacement of the piston in a direction, these pawls disengaging from the said notches, upon displacement of the piston in the opposite direction; this piston thus brings back to its starting position the pawl-carrying ring, but not the table which remains stationary until the following displacement of the piston for permitting the operators to effect their work on the hide which has been brought before them.

In order that th'einvention may be clearly understood, a form of construction of the dyeing machine forming the subject-matter of the said invention will be described hereafter with reference to the accompanying drawing in which: 7 n

Fig.4 is a partial section, on anenlarged scale, of a detail of construction of the table.

Fig. 5 is a section of thedriving device" and of its distributing member. I

1. As illustrated in the accompanying drawing, the improved dyeing machine .essentially' comprises a horizontal table composed of a number of sectors 1 bolted together and screwed on a crown 2 which receives anintermittent angular rotary movement, as will be explainedhereafter, with interposition of a bronze friction crown 3, on another't secured to-thecement foundation work 5.

The sectors 1 are each provided with a recess or housing in which is suitably arranged a glass plate 6 adapted to serve as support for the hides to be dyed and resting in wooden cross bars inserted at their ends in theribs provided in the. said sectors.

The table thus constituted intermittently receives about the central work 5 made of cement, an angular rotary movement of predetermined amplitude in order that the vari 1 one sectors 1 with the hide carried by each of them maybe successively brought opposite standing operators placed around the table, and corresponding in number to the number of sectorsof the latter, each operator being specialized in an operation or phase of the dyeing process. i y

This intermittent angular rotary movement is transmitted to the table by a driving piston 7 mounted in a: cylinder 8 and the piston 7 can be steamor compressed air ad- Initted through the pipe '15 in the shell 16 of a distributor, the plug 17 of which, controlled by a small electric motor 18 acting through the medium of suitable speed reducing devices, alternately admits the driving fluid on one or the other face of the said iston 7- thus resultin in the alternatin 7 V 2-) a displacement of-the latter in its cylinder 8.

Daring the forward movement of this pis ton, the rack 10' actuates; through the mem 15% and the paste 1%; the man 2 and the shoe 19 adjustably mounted on the rack-l0.

The distributor 17, which rotates with a continuous movement, then sends the -driving fluid on the opposite face of the piston 7 which moves backward by driving the rack 10 and member 12 in reverse direction to the arrow X, butanot thewtable whichrreinains stationary until, through therotation of the V usedin the following manner:

' distributor, the driving fluid is again admitted on the :other'face of the piston.

The table rotating as just described, is

A" hide isplaeed byhandby a first operator on-one-of the glass plates of the table; after a determinedangular rotation ofthe said table, this hide is presented opposite a second operator who, during the period of stoppage of the table, subjects the hide to a whilst the-*first'operator places a new hide on the plate glass which comes in front of li-imyaftelra second angular rotation of the tQblGytllQ first hide comes opposite a third the-dyeingprocess, whilst the second operator subjects the, following hide to the first series of dyeing operations and the 'first operator places-a third-hide on the next plate glass coming in front oft-him, and so on,

each of the hides being successively brought a opposite operators each specialized in an operation of the dyeing process (placing in position of the hides, mordanting, application ion the dyeing solution, rinsing, removal of the hides, etc.)

I It will be understood from the foregoing Htheta-the above-described,machine allows the dyeing ,by 1.11and by means of brushes, sponges, etc., that it presents the Very imwortant advanta e of obtainiiw the desired 23 b ber of sectors constituting the table ;may: be
